WATCHIVIAKERS TOOL.

Specification of Letters Patent.

Patented April 30, 190'?.

Application filed November 27, 1905. Serial No. 289,153.

T0 ctZ whom it nfl/(ty col/,cerni- Be it known that I, WILLIAM ARTHUR, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have made and invented certain new and useiul improvements in l/Yatchmalers Tools, of which the following is a specilication.

My invention. relates to an improvement in watchmakers tools, and more particularly to a device generally known and referred to in the trade as a pendant-set assembler, by which is meant, a tool or device for assembling the material usually contained in the pendant oi a pendant-set watch. ln watches of this character, there is usually employed in the pendant, a winding stem, one end of which is threaded into the crown, the opposite end projecting into the movement, said stem being capable of longitudinal movement within the pendant, and when in one position, is adapted to wind the movement, and when pulled outwardly to the other position, is adapted to set the movement. To hold this stem in its several positions and adjustments, a slotted spring sleeve is threaded into the pendant and held stationary therein, the ends oit said spring which engage with the stein, being turned inwardly to fit in a groove formed in said stem to hold the latter in its several adjustments. By reason of the formation ol' the stem and spring, it is essential that some means be provided for opening or spreading the arms or sections of the spring, in order that it may be slipped over the stem to be properly assembled therewith prior to being 'fitted in the pendant. For this purpose a very small device is used by the watchmalier or repairer, which by reason of its small size, continually becomes lost or mislaid on the work-bench, and further, by reason of the dill'erent size stems which are employed in dill'erent size watches, it is necessary that several ot these small devices be employe d The object oi my invention is to provide a device consisting of a plurality ell posts or standards, constructed in a novel way and oi' di'llerent sizes, to accommodate the several sizes of stems, these posts or standards being mounted in a ring or base to properly hold them in their upright or working position, and whereby the material may be more easily and readily assembled than has heretofore been possible.

l l l With these and other ends in View, the invention consists in certain novel features o'll'construction and combinations oi parts, as will be hereinafter fully described and pointed out in the claim.

,ln the accompanying drawing, Figure l is a view of my improved tool. Fig. 2 is an enlarged view of one oi: the standards and also ol a spring prior to the latter being slipped thereon. Fig. 3 is a view partly in section and partly in elevation olt one of the standards, having slipped thereon the spring, and showing the stem in position on said standard to allow the spring to be assembled with said stem. Fig. l is a similar view showing the spring and stem after being assembled.

The tool or device consists of a suitable base or support A, that in Fig. l being illustrated as a 'llat ring, and into which are threaded or otherwise secured the posts or standards B, one or more in number, preferably lour, the upper ends of which are reduced in diameter forming the shoulder c, this reduction in size being graduated or increased in the case of the several posts. These upper reduced ends l) of the posts B, are also drilled out or otherwise made hollow to a certain depth, as shown at d, these openings in the several posts being graduated in size in order to accommodate the threaded ends C of the winding and setting stems D, which latter, before described, are made of di'llerent sizes for use in the di'l'l'erent size watches.

In practice, when it is desired to assemble the stem D and spring E, the latter is lirst slipped down over the proper' size standard or )ost B until the shoulder c olt the spring stri (es the shoulder e el the post, the rcduced end l) of the ost thereby spreading apart the ends olt saidspring, as clearly illustrated in Fig. $3. The threaded end C oli the stem D is then inserted in the opening d ol the post, the shoulderu'folf the stem D resting upon the upper extreme end otl said post B. The ends ol the spring' E being' thus separated, the spring may now be easily and readily slipped o'll' ol the reduced end l) of the ost B and over and upon the stem D, as illustrated in Fig. el, after which the stem with its assembled spring, is lifted out or removed trom the post B.

From the foregoing it will be understood that the invention is exceedingly simple in construction, cheap to manufacture, and that, by means thereof the stems and springs l shoulder c between its ends and having the assembled. Furthermore, by reason of the portion above said shoulders reduced in diposts and stems being securely fastened to a ameter, the reduced portions of the several base, there is little or no danger of their beposts being of unequal diameters, each of said coming lost or mislaid, the tool in its comi posts plete form being of such a size that it can be modate the winding and setting stem of a readily seen or found on the workmans watch, said openings being of dil'lferent sizes, bench. and said shoulders serving as seats for the in- Ha'ving fully described my invention, what ternal shoulders of Winding stem spring.
